Abstract:
In this paper, weighted least square analysis is usad to study the genotype-environment interaction of major economic traits of Angora rabbit for three generations in two environments. The heterosis of the economic traits was analyzed by the estimated parameters and the theory of relativa heritability. The results indicate that there are significant additive effects and interactions between the additive effect and the environment among soma traits of wool producing performances of Angora rabbits, and significant environment effects existed in soma reproductiva traits. The heterosis of the wool yield is mainly due to gene dispersion, and the increase of reproduction performances is dependent on the improvement of environment. The theory of relativa heritability could be usad conveniently for the heterosis analysis, but significance test and the genotypeenvironment interaction could not be conducted or analyzed, which is the shortage of the theory.
